FILLING-BEPLENISHING LOOM.

Application filed September 23, 1913.

To all whom it may concern Be it known that I, OSCAR Brennan, a citizenof the United States, and residing at Fall River, county of BristolState of Massachusetts, have invented an Improvement inFilling-Replenishing Looms, of which the following description, inconnection with the accompanying drawing, is a specific-a tion, likecharacters on the drawing representing like parts.

This invention relates to improvements in filling detecting mechanismfor looms whereby the absence of filling is detected and a change in theoperation of the loom automatically caused to replenish the eX- haustedshuttle or to substitute a full bobbin for an empty one.

This invention, while not restricted to such use, is particularlyadapted for double detector looms of the Northrop type, wherein twofilling detectors are employed to detect filling failure on alternatepicks, one of said detectors directly controlling the operation ofmechanism for changing the operation of the loom, the other, orauxiliary detector upon detection of failure of filling causing suchmechanism to be operated by or through the first named detector. Inlooms of this character the n ain detector has been operated from theauxiliary detector by the outward movement of the auxiliary fork slideimparting a partial rotation to the rock shaft which controls thefilling replenishing mechanism thereby retracting the main filling forkso that the same will not touch the filling when the weft-hammers arecarried to their forward position. The filling fork therefore will notbe tilted and upon the retraction of the weft-hammers the tail of thefork will engage the hook and thereby cause the main fork slid-e tocomplete the rotation of the controlling rock shaft for the replenishingmechanism and effect the substitution of a new bobbin in the shuttle.

One of the principal objects of my invention is to provide an attachmentwhich can be applied to a filling fork detector loom. without materialmodification thereof and which will positively insure the operation ofthe main filling fork upon detection of absence of filling by theauxiliary filling fork.

Another object of the invention is to provide means for positivelylocking the main filling fork in engagement with its book Specificationof Letters Patent.

upon detection of absence of filling by the auxiliary filling fork andmaintaining it in locked condition until the replenishing action hasbeen completed.

iltnother object of the invention is to provide .n'icans positivelyactuated by the con troller for the replenishing mechanism to claims.

In the drawings: Figure l is a top plan view centrally broken out of asufficient portion of a double detector loom to illustrate my inventionand its application to an automatic filling replenishing loom. Fig. 2 isan end elevation partly in section of my inven tion as applied to aloom, showing the relative positions of the filling fork and the lay,and also including in dotted lines an illustration of the position ofthe rod for disengaging the auxiliary fork tail from its hook, upon thecompletion of the replenishing operation. Fig. 3 is a detail View of theauxiliary filling fork, its hook, and the pit-(1a for dis-engaging thefork tail from the 100 r.

Referring to Fig. 1 the partly illustrated hopper 1 at the right is ofthe well known Northrop construction having a transferrer f2 operatedthrough a replenishing controller rock shaft 3 which is rocked by themain filling fork mechanism preferably located at the shipping side ofthe loom. These parts may be of the ordinary construction used inautomatic filling replenishing looms.

As illustrated in the drawing the main detector is provided with afilling fork 4 mounted upon a slide 5 guided in suitable ways in theframe of the machine. The vibrator 6 is provided with the usual hook 7adapted to engage the tail of the filling fork 4 upon absence of fillingin the usual manner common to this type of loom. The operation of themain filling fork is therefore that of the ordinary fork used in theNorthrop loom to wit: Vvhen the fork l is engaged by the filling uponthe forward movement of the lay it is tilted and the tail lifted, sothat when the hook carried by the vibrator 6 beins its'outward strokethe hook 7 passes beneath the tail of the fork without engagementtherewith. If, however, there is an absence of filling the fillingfo-rkt will not be tilted and upon the outward movement of the vibrato-rits tail will engage the hook 7 of the vibrator 6; the slide will beforced outward until its end engages an arm 8 upon the rock shaft 8,thereby causing the operation of the filling replenishing mechanism.

The auxiliary fork 10 used in connection with this invention may belikewise mounted upon a slide 11 of the ordinary construction andadapted to cooperatewith avibrator 12 carrying a hook 13 of the usualconstruction, the essential features of my invention residing in themechanism by which the operation of the, auxiliary fork upon detectionof absence of filling effects the depression of the tail of the mainfilling fork into engagement with its cooperating hook to cause thereplenishment of the shuttle. In a preferred embodiment of my inventionwhich is illustrated herein the absence of filling causes the engagementof the tail ofthe auxiliary fork 10 with the hook 13, and, upon theoutward movement of the vibrator, the retraction. of the slide 11 sothat the endthereof 1 1 is caused to contact with an arm 15 projectingupwardly from an auxiliary rock shaft 16 and rock the same against thetension of a helical spring 17. The rock shaft 16 is ournaled in lugs 18secured upon the frame of the machine at suitable points by bolts orother fastening devices and is connected to aclamping member which isadapted to depress and lock down the tail of the main filling fork 1 andthereby cause the main detector to actuate the filling replenishingmechanism. This clamping mechamsm and its actuating devices are arrangedas, follows: A support 19 secured upon the breast beam is provided withan upward projection 20 terminating in the bearing 21..

Pivoted upon said bearing is an inverted L- shaped member, the forwardend. 22 of which is adapted to engage the tail of the filling fork andhold the same in depressed position. The downwardly projecting arm 23 ispivotally attached to a link 24 which is connected with the end of anarm 25 secured to the auxiliary rock shaft 16. It will be obvious thatby this connection the rocking of the auxiliary rock shaft by theoutward movement of the slide 11 of the auxiliary filling fork willresult in the retraction of the arm 25 against the tension of thehelical spring 17, causing through the link 24 the depres- S1011 of theclamping member 22 upon the fork tail. This willcause a positivelocking.

engagement between the tail of the main filling fork at and the hook 7and upon the fork 10 will remain in engagement with the hook 13 and themain fork againcalled upon to operate the replenishing mechanism untilreplenishment is effected.

In order to avoid the possibility that the tail of the auxiliary fillingfork may become locked with its cooperating hook and thereby causerepeated actuation of the replenishing mechanism means-are providedwhereby the controller shaft for the replenishing :mechanism disengagesthe tail of the auxlliary fork from 1ts hook slmultaneously with thereplenishing of the shuttle. In the embodiment of this invention shownin the drawing the controlling rock shaft 3 for the replenishmentmechanism is provided with ,a laterally extending arm 26 which engagesthe lower end of an upwardly extending rod 27 which terminatesimmediately beneath the tail of the auxiliary fork. The rod 27 ispivotally secured to the end of the arm 26 and passes freely through aguide 28 on the slide 11. It may if necessary, be offset, as at .29, toavoid contact with the lay when the latter comesforward to beat up thefilling.

Upon the rotation of the controlling rock shaft to effect thereplenishing of the shuttle the outer end of the arm 26 will be raised,thus forcing the rod 27 upwardly and positively raising the tail of thefork 10 from its engagement with the hook 13, thus restoring the fork toits normal detecting position. Suitable mechanism may be provided, as iscustomary in a loom of this character, for disengaging the takeup whenabsence of the filling is detected in the loom. This, however, can be ofthe ordinary construction and forms no part of my present invention.

This invention may be applied easily to any filling fork replenishingloom whether the same is a double feeler loom or a single feeler loom.In the former case the usual filling fork mechanism may be employed withsuch slight modification as is necessary to incorporate the featuresabove described. In the latter case it is merely necessary to introducean auxiliary standard filling fork mechanism, place a grid, such as 30,in the necessary place at the end of the lay and supply bearings for theauxiliary shaft 16 and bolt the clamping mechanism to the frame in themanner set forth above.

While this invention has been described with particular reference to itsapplication to the replenishing of filling in automatic looms, and thereplenishment of filling in the shuttles of automatic looms, it isobvious that the invention. is not confined to this use, but that it maybe utilized for changes in the operation of the loom, as for example,the operation of mechanism for stopping the loom upon detection ofabsence of filling. It is to be understood therefore, that th1sinvention may be of general application to effect changes in theoperation of looms found desirable or necessitated by the fail are offilling.
